In a sea of Sudoku apps, this one stands out for its elegant simplicity and attention to detail. It doesn't clutter the screen with ads or unnecessary social features; it focuses entirely on the puzzle-solving experience. The note-taking system is the best I've used on a touchscreen—it allows for quick pencil marks that automatically update when a number is placed in a related cell.
The difficulty curve is excellently tuned. 'Easy' is perfect for a five-minute brain warm-up, while 'Expert' requires advanced techniques like X-Wings and Swordfish. The game also includes a 'Smart Hint' system that doesn't just give you the answer, but explains the logic behind why a certain number must go there, making it a great tool for actually improving your Sudoku skills.
Reviewing a Sudoku app is like reviewing a hammer. Does it hit the nail? Yes. This app doesn't have any bells or whistles, and for someone like me, that’s actually a good thing. It’s not trying to be a 'battle royale Sudoku' or whatever nonsense they’re coming up with today. It’s just numbers in a grid. The input method is efficient, and it hasn't crashed on me once. It’s boring, but Sudoku is supposed to be quiet. If you want a flashy game, look elsewhere. If you want to do a puzzle in peace, this is fine.
Performance: Perfect stability.
Buy if: You want a basic, functional Sudoku app.
Skip if: You already have a Sudoku app (they are all the same).

________________________________
To the classic Sudoku, we added:
=> A smart point system, wherein your score is based on 1) the value of each number multiplied (at the time of its match) by a multiplier that decreases in time and 2) the value of each block, row, column multiplied (at the time of its completion) by the decreasing multiplier
=> Thanks to Game Center, you can now rank and compare Sudoku scores and achievements against friends and strangers
=> ▻Sudoku also counts the runs, that is, each uninterrupted sequence of games won, and adds them to the online leaderboards
________________________________
In ▻Sudoku, you win a game when you solve a puzzle with 3 errors or less (we used this threshold to give a bit of slack for mis-tapping :) Also, you have a number of hints to help you play (more at the easy, less at the hard level). To fit any taste, you can choose between a lush tile look or a more classic board look :)
